Abstract
The Doppler frequency shift of signals propagating from an Emergency Locator Transmitter (ELT) on a downed aircraft up to a transponder on a search and rescue satellite (SARSAT) and down to a central station is affected by the ionosphere. In the report ionospheric effects are estimated for a proof-of-concept SARSAT experiment using the AMSAT OSCAR-6 satellite. The results obtained here can be applied to the definition of an operational SARSAT system.
